Hi there,

You are running this on a cloud service, is that correct? In the past we have found that we needed to increase RAM to about 4Gb in order to install dependencies - we should probably mention this in the help message that follows, as this comes up a bit.

Are you using 4Gb of RAM on your cloud service? If not, then that would be great to be able to run it with more RAM?

Let me know how you go!
